I want to monitor the number of NAT entries on my Cisco 5585-X ASA. I found the correct OID for the SNMP custom sensor. However, the number of NAT entries is in the Message field, and the Response Time data is graphed. I want to be able to graph the NAT values. How can I do this?

Dear Brian
Did you use an SNMP custom sensor, or an SNMP custom string sensor? The message cannot be graphed, it is not even stored in the historic data. Only channel values can be graphed.
However with an SNMP custom string sensor you can extract a numerical value from the string using a regular expression. Please find this option in the configuration. Depending on how the output is formatted, the regex could be [0-9], or just \d (please search for "regular expression" in the internet.)
